Abstract

Abstract: Sulfur‐doped graphitic carbon nitride (S‐g‐CN) has gained significant attention in recent years. Sulfur‐doped graphitic carbon nitride (S‐g‐CN) is a promising metal‐free photocatalyst because of its band orientation, natural abundance and groundwork. Improved photocatalytic activity of S‐g‐CN material for solar chemical production persists a hot yet challenging problem. Herein, we provide an adaptable method for the synthesis of S‐g‐CN nanocomposite decorated with the moiety of giant polyoxometalate (S‐g‐CN/Mo‐368) that subsequently showed highly efficient photocatalytic activity. The as‐synthesized S‐g‐CN/Mo‐368 as a recyclable artificial photocatalyst revealed excellent activity for solar chemical production, that is nicotinamide adenine dinucleotide (NADH) regeneration under visible light. The immobilized Mo‐368 on the S‐g‐CN surface increased the visible light adsorption capacity of the S‐g‐CN/Mo‐368 photocatalyst. The visible light absorption activity, morphology, element compositions, particle size and zeta potential of S‐g‐CN powder and S‐g‐CN/Mo‐368 were thoroughly investigated. From the application point of view, S‐g‐CN/Mo‐368 was applied to determine the solar chemical production (i.e. NADH regeneration) under visible light with a higher yield% of about ~ 94.85%. Abstract : As a recyclable artificial photocatalyst, the as‐synthesized S‐g‐CN/Mo‐368 showed excellent behavior for solar chemical production (i.e. NADH regeneration) under solar light. In addition to exhibiting efficient photocatalytic activity of S‐g‐CN/Mo‐369 photocatalyst against S‐g‐CN powder, the adsorbed, Mo‐368 material also offers enhanced photocatalytic activity against the reaction of triazine units in condensed g‐CN heterocycles and tri‐s‐triazine heterocyclic ring (C‐N) units. Above figure provides the pictorial presentation of a photosynthetic system based on the naturally and artificially engineered Z‐scheme for the regeneration of nicotinamide cofactor and the conversion of NAD + to NADH chain reaction.
